Apple iOS fans this week overloaded Apple's servers trying to upgrade their gadgets to iOS 7; at Ohio University, the rush reportedly took down the school's Internet service. While some clueless upgraders were shocked by the mobile operating system's new "flat" design and colorful new logos, others had a more pressing concern: a big drop in battery life.

"The only bad thing about iOS 7 is that it drains my battery," one Twitter user remarked today.

"There's a bug with iPhone 5 when running iOS 7 in which the battery life is significantly shorter and charge times longer," another user chimed in.

The problems do not appear to be affecting all those who upgraded to iOS 7. In fact, some took to the micro-blogging site to remark that iOS 7 actually improved their phone's battery life. Here at PCMag, we have not seen any significant battery life problems for those who made the switch to iOS 7; my AT&T iPhone 5 has been running as usual.

One solution for those experiencing battery drain is to navigate to Settings > General > Background App Refresh. This feature allows apps to refresh their content in the background, but Apple acknowledges that turning off for certain apps can help preserve battery life. Apps that take advantage of this feature include Google Maps, Apple's built-in Stocks app, The Weather Channel app, Yahoo's new weather app, and the new Google Wallet for iOS.

This is not the first time that an iOS refresh has resulted in battery drain. Back in Nov. 2011, Apple released an iOS 5 update that fixed a battery-draining bug.
